Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterTrusted Chimney Cap & Crown for Sterling Homeowners
Chimney Cap & Crown in Sterling typically costs $275-$1,400 depending on whether you need a simple cap replacement or a full custom crown rebuild, and most jobs are completed in a single afternoon. The crown is the concrete slab at the very top of your chimney, and when it cracks, water gets behind the brick and freezes, turning a $300 fix into a $3,000 rebuild if you wait. Wendell Pike has been fixing caps and crowns across Sterling since 1999, and he will tell you plainly when the job can wait and when it can’t. Call (571) 518-5470 and you’ll get a live person, a straight answer, and a price before any tool comes off the truck.
Key Takeaways
- The crown is your chimney’s roof. A cracked crown leaks water into the brick, and Sterling’s freeze-thaw cycles do the rest.
- Caps do double duty. They keep rain, birds, and downdrafts out, and they stop sparks from landing on your roof.
- You don’t always need a full replacement. Crown coating and patch repair are real options when the damage is caught early.
- Every job is photographed. You see the camera footage and get a plain-English verdict before you approve anything.
- Backed in writing. Every cap and crown job carries the 90-Day Done Right Promise. If it’s not right, one call brings Wendell back at no charge.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is the metal cover that sits over the flue opening, and in Sterling where we get real rain, real wind, and the occasional nor’easter remnant, it is the cheapest insurance you can buy for your chimney. Without a cap, water pours straight down the flue, rusts the damper, and soaks the firebox. Wendell measures the flue, recommends the right size and material for your specific setup, and installs it so it stays put in a stiff wind, which matters more than people think up on a two-story roof line in Belmont or Brambleton.
Cap Replacement
A cap that is rusted through, bent from a falling branch, or simply the wrong size for the flue it sits on is doing you no favors. We remove the old cap, note any damage to the flue tile underneath, and set a replacement that actually fits, because a loose cap rattles in the wind and a too-small cap lets rain in around the edges. This is one of the most common jobs we do after a storm blows through Sterling and the surrounding neighborhoods, because caps take the brunt of whatever the sky throws at them.
Crown Repair
The crown is the concrete or mortar slab that caps the chimney structure itself, and when hairline cracks appear, water seeps in and does its worst over a Sterling winter, freezing and thawing until the cracks widen into gaps. Small cracks can be sealed before they spread, and a crown with moderate damage can often be patched and resurfaced rather than torn out and repoured, which saves you real money when the damage is caught in time. Wendell has repaired hundreds of crowns across Sterling and will tell you straight if the crown is salvageable or if it has gone too far, and the camera footage will show you exactly what he is seeing.
Crown Coating
A crown that is structurally sound but showing its age can often be protected with a flexible, waterproof coating that seals surface cracks and extends the life of the slab by years. This is a good option when the crown has minor surface wear but no deep cracking or spalling, and in Sterling’s climate it buys you time against the freeze-thaw cycle that does in most crowns eventually. The coating bonds to the existing concrete and flexes with temperature changes, which is exactly what you want on a chimney that gets hot on one side and cold on the other all winter.
Multi-Flue Cap
If your Sterling home has two flues, one for the fireplace and one for a furnace or water heater, you need a cap that covers both openings without sealing in moisture or trapping exhaust, and that’s a job for someone who understands how each flue breathes. A multi-flue cap sits across the entire crown and protects both openings while allowing proper draft, and it has to be sized right for the crown dimensions, not just the flue tiles. We install multi-flue caps on homes all over Sterling, and the difference between a good one and a bad one is whether your furnace still drafts properly on a cold night.
Custom Cap
Some chimneys in Sterling are shaped like nothing else on the street, stone crowns that are wider than standard, odd flue configurations, or a crown that has settled unevenly, and a stock cap simply will not sit right on them. For those jobs, Wendell takes exact measurements and orders a custom cap fabricated to match the crown and the flue layout, usually from Copperfield or Olympia Chimney, both of which he has worked with for years. A custom cap costs more than an off-the-shelf unit, but if a standard cap does not fit, the custom one is the only one that actually keeps the weather out.

Brands We Service for Chimney Cap & Crown
We work with Copperfield, Olympia Chimney, and Gelco caps and crowns most often, because these are the brands that hold up best in a climate like Loudoun County’s, where a chimney gets baked in July, soaked in October, and frozen in February. Copperfield makes a stainless steel cap that Wendell has been installing since the early 2000s, and he knows the sizing charts and mounting hardware by heart, which means you are not paying a sweep to learn on your roof. Olympia Chimney products are a frequent choice for multi-flue caps on older Sterling colonials, and Gelco crown coating products are what we reach for when the crown needs sealing but not rebuilding.
If you know the brand on your chimney now, mention it when you call, and Wendell will tell you whether it is worth saving or worth replacing, based on what he has seen on hundreds of similar setups. If you don’t know the brand, that’s fine too. Most homeowners don’t, and the inspection is when we figure out what you have and what it needs. Whether your cap came from a big-box shelf or a specialty fabricator, the question is the same: does it fit, does it seal, and will it still be doing both in five years.
Signs You Need Chimney Cap & Crown Right Now
- Water staining on the ceiling or walls near the fireplace. That stain is usually the crown or the cap failing and sending water down through the chimney chase, and in Sterling, where rain can come down hard for days, it only gets worse. By the time you see the stain inside, the water has already been working on the brick and mortar for a while.
- Chunks of concrete or mortar on the ground at the base of the chimney. Spalling concrete means the crown is actively breaking apart, and every piece that falls off is one more entry point for Sterling rain. This is the one Wendell says people ignore the longest, because the chimney still looks fine from the street, but it is not fine from the top.
- You hear birds or animals scratching inside the chimney. A missing or damaged cap is an open door for chimney swifts, squirrels, and in Loudoun County, the occasional raccoon, and none of them pay rent. A solid cap with proper screening ends that problem the day it goes on.
- Rain or snow falls inside the firebox during a storm. That is the most direct clue you will ever get that the cap is missing, undersized, or rusted through, and in a Sterling winter, that water is landing on your damper and firebrick every single storm. The damper rusts, the firebox spalls, and the repair bill climbs with every passing season.
- White efflorescence staining on the exterior brick near the top of the chimney. That white powder is mineral salt being pushed out of the masonry by water moving through it, and it means the crown or cap has been leaking for months or longer. Once the water is stopped at the top, the efflorescence stops spreading, but the longer it runs, the more of the brick face you lose.
Our Chimney Cap & Crown Process - Step by Step
- 1
Inspection and camera work. Wendell walks the roof, checks the crown, the cap, the flue liner, and the brick work up close, then runs a camera down the flue so both of you see exactly what is happening inside. This is the same routine he has used since day one, and he won’t recommend a repair without footage showing you why.
- 2
Plain-English report and written quote. You get a straight explanation of what is wrong, what can wait, and what needs doing now, with a written price before any work starts. The number on that quote is the number on the invoice, no surprise line items at the end of the day.
- 3
The work, done clean. Old cap removed or crown prepped, new cap installed or crown repaired and coated, all the debris carried off and the area swept. Wendell and his crew lay drop cloths, wear shoe covers, and treat your home like they have to face you at the hardware store on Saturday, because in Sterling and the surrounding towns, they usually do.
- 4
Photo report. When the job is done, you get photos or video of the finished work, the new cap or sealed crown, and the flue interior if the liner was involved. No guesswork, no taking anyone’s word for it, just a record of what was done up there.
- 5
90-Day Done Right Promise, in writing. Every cap and crown job we do carries the same promise: if it is not right, one call brings Wendell back at no additional cost. It is stamped on the paperwork and it means what it says.
How Much Does Chimney Cap & Crown Cost in Sterling?
A standard stainless steel cap installation in Sterling runs $275-$550 depending on flue size and roof access. A crown repair with patching and sealing typically falls between $400 and $900, while a full crown tear-out and repour on a two-story chimney can run $1,200-$2,500 because of the labor and material involved. Custom caps, which we order most often for odd-shaped or multi-flue crowns around Brambleton and Great Falls, usually land between $600 and $1,400 installed. These are honest ranges for this area, not marketing numbers, and the best way to get your exact price is a free in-person look, not a quote over the phone from someone who has never seen your chimney.
What moves the price is the size of the flue, the condition of the crown, how high and steep the roof is, and whether the old cap needs fabrication or an off-the-shelf unit will do. If you already have a written estimate from another company, bring it, and we will give you a free second opinion on it. You may find that what they priced as a full rebuild is actually a simple crown coating, and that is the most common place national outfits inflate the bill. Every estimate we give is free, and the price you hear before the job is the price on the invoice, period.

Frequently Asked Questions - Chimney Cap & Crown in Sterling
The crown is the concrete slab at the very top of the chimney that slants water away from the flue, and the cap is the metal cover over the flue opening that keeps rain, animals, and sparks out. They work together as the top line of defense against Sterling weather, and when either one fails, water starts moving into places it should not. Both are relatively inexpensive to fix compared to the damage they prevent.
Most cap installations and crown repairs are done in a single visit, usually two to four hours depending on the job and the roof. A full crown rebuild with curing time can take most of a day. Wendell will give you a real arrival window when you book, and if anything slips, someone calls you before the window closes.
A standard cap installation runs $275-$550, crown repairs run $400-$900, and full crown rebuilds run $1,200-$2,500, with custom and multi-flue caps landing between $600 and $1,400 in most Sterling homes, per our Chimney Cap & Crown cost guide. Your exact price depends on flue size, crown condition, and roof access, and the best way to get it is a free inspection. Call (571) 518-5470 for an exact quote, and remember there is no trip charge inside the county.
Yes, we install and service Copperfield caps, Olympia Chimney caps and accessories, and Gelco crown coating products, along with equipment from other major manufacturers. Wendell has worked with these brands for years and knows which one fits which chimney without guesswork. If your cap is from a different brand, call us anyway, and we will tell you whether it is worth keeping.
A live person answers our phones 24/7, and if a storm has taken your cap off or water is pouring into the firebox, you will talk to a real human, sometimes Wendell himself, not a call center or a voicemail. We will schedule you as fast as the calendar allows and give you a straight answer about whether the damage can wait a day or needs attention sooner. Serious water intrusion into the chimney should not be ignored, but the goal is to get you on the schedule and get it fixed, not to rush a job on a wet roof.
Every cap and crown job carries our 90-Day Done Right Promise in writing, which says that if the work is not right, one call brings Wendell back at no additional cost. The manufacturers we work with also stand behind their products, and we will walk you through what is covered on paper before you sign anything. If something fails down the road, the promise is simple: we come back and we make it right.
You do not need to do much: just clear the area around the fireplace inside in case we need access to the flue, and make sure the roof is accessible from a ladder if the pitch allows. Wendell and his crew bring drop cloths, shoe covers, and all the tools, and they will let you know if there is anything specific about your setup, like a fenced yard or a dog, that they should know before arriving. After the work, you get photos of the finished job and a copy of the Done Right Promise for your records.
